RE: Generate audio output using PIC Thursday, July 24, 2008 11:46 PM ( permalink ) 0. You can use PWM to generate complex audio such as speech, and even to replay music etc. Simplest PWM solution includes an RC circuit followed by an audio power amp. Better output has an antialiasing filter after the RC and before the power amp.
Back to Basics – Audio Output on the Raspberry Pico using PWM

This time I want to describe an approach which is a little bit more versatile: The Pico provides no built-in DAC and thus we have no real analog output, but we can generate PWM signals on all pins – so if we use a basic PWM frequency which is well above the hearing range (which is 20 – 20’000 hz) we can get a very similar result. The Pico ...

Averaging the PIC PWM output. To convert the PWM signal to a usable analogue signal you need to average it and you can do this by using a resistor capacitor filter (low pass). The higher the PWM frequency the less that frequency will come through the filter so you can design out the PWM frequency from the analogue output.
Audio using PWM, what is the principle behind it ...

I have seen a schematic of a PIC board which uses filtered PWM to provide audio output signal to an audio jack. It shows PWM output filtered using 3 stages of passive RC filter followed by an LM386 stage. I have the following questions: Usually an audio signal would have multiple frequencies summed up simultaneously. How does PWM do that?

Pulse Width Modulation (PWM) Pulse Width Modulation (PWM) is a common peripheral on almost every PIC ® MCU device. PWM is a way to use a digital output to vary the on, or high time, to create a variable output or square wave (as seen in the figure below). If the PWM signal runs at a fixed frequency, then changing the high time of the signal ...

The audio is generated using PWM technique, basically the PIC18F4550 has two PWM modules and their output are RC2 and RC1 for PWM1 and PWM2 respectively. An audio amplifier is needed to amplify the audio. In my circuit I used PC speaker as an amplifier.

The PWM Period = 2us. Thus in a Sampling time number of PWM cycles can be calculated as 40/2 = 20 PWM cycles. Number of PWM cycles per Sample = 20. Thus the timer0 will generate an interrupt after every 20 PWM cycles. This much number of PWM cycles per sample is good enough to generate a stable output sample voltage from a filter device.

On the other hand, there are many asm examples out there for soft-pwm, where interrupts are used to generate a pulse-train. the advantage to soft-pwm is cheaper chips can be used, and you can get more pwm outputs. an inexpensive 12f683 has only one hard-pwm output, but can do five soft-pwm outputs.
